The article reports on the research on current-driven nanotubes in New York City. It states that researchers have streamlined carbon-nanotube emission by integrating a carbon-nanotube emitter with a planar microcavity as a first step toward the development of nanotube-based photonic devices. They also estimate that current-driven nanotubes integrated in silicon nanocavities with a high quality factor could lead to low-threshold on-chip nanolasers or at least high efficiency on-chip nanoemitters.

It provides an overview of how a team from Rensselaer Polytechnic Institute in New York grew CNTs using chemical vapor deposition methods in quartz-tube furnaces using two different recipes.

The article reports on the results for NaturalNano Inc.'s manufacturing scale testing of Pleximer in Rochester, New York. The results had revealed an excess of 30% of halloysite nanotubes in nylon, which led to the improvement of strength and modulus properties in the resulting nanocomposite without sacrificing the natural elongation of nylon. Moreover, the company will conduct further trials with polypropylene and plans to offer Pleximer in the market in the fourth quarter of 2007.
